It is an excellent choice for businesses with a main headquarters and multiple branch offices. EVPL is reliable, is flexible, and is a higher bandwidth alternative to time-division multiplex (TDM) private lines. EVPL is also sometimes called a Virtual Private Line or VPL.

Fiber lines, aka optical fibers, are small lines made of glass. They are bundled together in a fiber-optic cable. These lines transmit data as pulses of light and can transmit more data faster and over longer distances than other modes of transmission. They are used for fiber-optics phones, TV, and internet. 

High-speed internet is internet service that downloads at speeds of 25 Mbps (Megabytes, or megabits, per second) or faster. High-speed internet is offered through DSL, cable, satellite, or fiber-optic lines.
